Reports implicit conversion between numeric types.
<p>Implicit numeric conversion is not a problem in itself but, if unexpected, may cause difficulties when tracing bugs.</p>
<p><b>Example:</b></p>
<pre><code>
  double m(int i) {
    return i * 10;
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  double m(int i) {
    return (double) (i * 10);
  }
</code></pre>

<p>Configure the inspection:</p>
<ul>
  <li>Use the <b>Ignore widening conversions</b> option to ignore implicit conversion that cannot result in data loss
    (for example, <code>int</code>-&gt;<code>long</code>).</li>
  <li>Use the <b>Ignore conversions from and to 'char'</b> option to ignore conversion from and to <code>char</code>. The inspection will
    still report conversion from and to floating-point numbers.</li>
  <li>Use the <b>Ignore conversion from constants and literals</b> to make the inspection ignore conversion from literals and
    compile-time constants.</li>
</ul>
